If
the engine speed is low, adjust
it
to the rated r.p.m.
*Refer to Step

11-3-2 CHECK THE TOTAL WAnAGE
OF
APPLIANCES CONNECTED TO THE GENERATOR.
Refer to Section

"RANGE
OF
APPLICATIONS" for the wattage of the appliances.
If
the generator is overloaded, reduce the load to the rated output of the generator.

CHECK THE INSULATION
OF
THE GENERATOR.
(1)
Stop the engine. Remove the control panel;
and disconnect the connector of GREEN lead
for ground.
(2)
Measure the insulation resistance between the
live terminal
of
the receptacle and the ground
terminal.
If
the insulation resistance is less than
1
M
Q
,
disassemble the generator and check the in-
sulation resistance of the stator, rotor and the
live parts in the control box. (Refer to Section
Any part where the insulation resistance is less
than
1
M
SZ
,
the insulation is faulty and may
cause electric leakage.
Replace
the
faulty
part
